6 Claims. (Cl. 137-604) This invention relates to a cleansing or washingtool or instrument.

An object of the present invention is to provide a hand tool forcleansing purposes that optionally provides a supply of clear water, asolution of water and one ingredient such as soap or detergent, forinstance, and a mixture of water and another ingredient such as asterilizer, the invention contemplating a tool that is timesaving andhighly eflicient for the intended purpose.

Another object of the invention is to provide a washing or cleansingtool of the character referred to that has its controls so arranged thatonly one solution or the other may be discharged at one time.

A further object of the invention is to provide a washing tool in whichthe controls may be manually manipulated to provide a sequentialoperation of first water alone, then one solution as above, and finallythe other solution.

A still further object of the invention is to provide a tool thatdischarges two different solutions, sequentially, one for cleansingpurposes and the other for sterilization.

The invention also has for its objects to provide such means that arepositive in operation, convenient in use, easily installed in a workingposition and easily disconnected therefrom, economical of manufacture,relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novelcombinations and arrangements of parts, which will more fully appear inthe course of the following description. However, the drawing merelyshows and the following description merely describes, preferredembodiments of the present invention, which are given by way ofillustration or example only.

Figs. 3 and 4 are similar cross-sectional views showing the tool indifferent operative positions, Fig. 3 to discharge one solution and Fig.4 another solution.

Fig. 5 is a broken plan View of a modification.

The instrument or tool that is illustrated comprises, generally, ahousing 10, a normally-closed Water valve 11 located adjacent one end'ofthe housing, an inlet 12 to said valve 11, a handle 13 for controllingthe valve, an inner body 14 adjacent the other end of the housing andreceptive of flow from valve 11 when the latter is opened bymanipulation of the handle 13, a valve 15 in the body 14 and an inlet 16thereto for supplying a flow of one ingredient, such as a liquiddetergent, to the interior of the body, a valve 17 in the body 14 and aninlet 13 thereto for supplying a flow of another ingredient, such as aliquid sterilizer, to the interior of the body, the handle 13 beingextended to control the valves .15 and 17, and a discharge-passingextension 19 on the end of the housing 10 beyond the body 14 andprovided Patented Mar. 21, 1961 ice The housing 10 is preferably formedas an elongated,

interiorly-hollow member of desired hand-gripping size and form. Thedetails of its shape may vary providing the same is made to house thevalve 11 and body 14 together with the connections and controlstherefor. Said housing may be metal and is advantageously made ofnon-metallic or plastic material for good wear and heat insulation whereneeded. a

The valve 11 is shown as having a valve body 21, wholly or partly housedwithin housing 10, a valve disc 22 interiorly of said body 21 andnormally biased to a closed position against a valve seat 23 formed insaid body, an inlet port 24 and an outlet port 25. Structurally, saidvalve is generally conventional and, when its valve disc22 is displacedfrom its seat 23 against the bias of spring 26, flow is established frominlet 12 to a tube 27 extending from the outlet 25.

The inlet 12 preferably comprises a flexible hose 28 that, by means of afitting 29, is connected to the valve inlet 24. Of course, the hose maybe connected in the usual way to a source or supply of liquid, such aswater. In practice, the inlet 12 preferably has central alignment withthe housing 10, substantially as shown.

A valve stem 30 is guided. by the valve body 21 in impingingrelationship with the valve disc 22 and extends outwardly of thehousing, preferably radially. The handle 13 comprises a lever 31 mountedon a hinge pin 32 mounted between support ears 33 that extend from thevalve housing 21 through the housing 10. Said lever 31 extendslengthwise of and above the housing and in operative engagement with thestem 30. It will be evident that manual depression of the lever againstthe'bias of a leaf spring 34 causes depresison of said stem and openingof the valve 11.

The inner body 14 is shownas in the form of a block 35 that is connectedto the flow tube 27 and is provided with a longitudinally disposedVenturi passage 36 that receives the flow from said tube. The outlet endof passage 6 is provided with an air intake hole 37. A tubular extension38 is provided for the Venturi passage beyond its discharge end.

The valve 15 comprises a spring-biased ball 39 that closes the end of abushing 40 in a bore 41 in the body block 35. A stem 42 is guided insaid bushing and extends outwardly of the housing 10. As can be seen,the valve 15 is disposed to one side of the throat portion of theVenturi passage 36 and the interior of the bushing is connected to saidpassage by a port 43. 'It will be noted that normally the valve isclosed and the stem 42 is held by the ball 39 clear of the port 43. Whenclosed, as in Fig. 2, said valve prevents flow from inlet 16 to thethroat of Venturi 36. When the stem 42 is depressed by the handle lever31, as in Fig. 3, the ball is unseated and flow from outlet 16 to theVenturi is established, the rate of flow being a function of thepressure drop or suction eflfect dependent upon amount and speed of flowof water through the venturi.

When the lever 31 is fully depressed, the barrel or wider portion of thestern 42'closes off the port'43, thereby closing the valve 15. Thus,upon operative movement of the lever, valve 15 is first opened byunseating the ball 39 and is then closed by the stern closing port 43,The latter position is shown in Fig. '4. The operator may be apprized ofthe movement of said valve from open to the closed position of Fig. 4 byany suitable means, such as a click device or other'momentary stop.

The details of construction of valve 17 are'substantially similar tothose'of valve 15. The only change is in the length of the stem 42a, thesame being shorter than stem 42. Valve 17 has only the closed positionof Figs. 2 and 3, which is maintained during movement of the valve 15from its normally closed to the open position of Fig. 3, and the openposition of, Fig. 4 wherein the final operative movement of the handle31 causes the stem 42a to unseat the ball39a to open flow from inlet 18through a port 43a to the throat of Venturi-36. During the latterposition of valve 17, the valve 15 is closed, as above described. Hence,only inlet 16 or inlet 18 is open, at any one time, to flow into Venturi36 for admixture of the flow in said inlets to the flow in the Venturi.

Of course, when the handle 13 is released, both valves 15 and 17 closeand remain closed until the handle is again depressed.

The modification of Fig. 5 will be provided with valves a and 17a thatare normally closed but can be moved only to open position by the handle13a. Said valves 15:: and 17a are alike except that the stems thereofare of unequal length so that one can open before the other opens. Saidstems may be made of the same length if the handle is so formed as tocontact and depress one stem before the other is contacted anddepressed.

By providing a stop 44 that limits operative movement of the handle, thevalve 15a may be opened without the valve 17a being opened. After flowfor cleansing purposes is allowed to continue as desired, the handle 13amay be shifted laterally, as on a hinge 45, to lose contact with thestem of valve 15a, thus allowing said valve to close. This lateralshifting of the hnadle removes the same from engagement with the stop44. Now, the handle may be further depressed to open valve 17a. A spring46 returns the handle to its initial condition as the same is releasedto allow spring 34 to raise the handle, as before described.

The modification provides a construction that enables opening valve 17awithout disturbing valve 15a, and vice versa.

Thus, the extension 19, in the form of a tube, receives flow that may bewater alone or a solution of detergent or sterilizer, sequentially, oras desired. The change from one to the other flow is instantaneous, ascontrolled by movement of the handle.

The implement is shown as a brush, but the same may vary and,consequently, may be interchangeably connected to the housing 10 or theextension 19, as desired.

While the foregoing specification illustrates and describes what we nowcontemplate to be the best modes of carrying out our invention, theconstructions are, of course, subject to modification without departingfrom the spirit and scope of our invention. Therefore, we do not desireto restrict the invention to the particular forms of constructionillustrated and described, but desire to cover all modifications thatmay fall Within the scope of the appended claims.
